无法链接我自己的静态库

Unable to link my own static libraries

我正试图在windows中为GLFW/ONGL项目添加一个声音库。我已经将声音项目设置为输出静态库（.lib）。它编译得很好。

在我的主要项目中，我添加了对Sound的引用和对Sound的依赖（以更改构建顺序）。我在我的main.cpp中包含了"..\Sound\Sound.h"，Intellisense对一切都很满意。所有的编译都很好。然而，链接器很生气：

我不知道该怎么办。Lnk2038应该意味着调试和发布之间的问题，但一切都处于调试模式。lnk2019对Sound.lib应该没问题吗？

非常感谢！

您的库一切正常（除了混合调试和发布运行时）。在调试模式下生成程序时，必须链接调试生成。发布版本也是如此。这是针对错误LNK2038和警告LNK4098的。

其他错误是由一个简单的事实引起的，即您不能将静态库与静态库（此处：OpenAL）链接，因为如果两个静态库引用同一静态代码（本质上导致多个定义），这将变得格外复杂。

要解决这些错误，您需要做的很简单：将生成的可执行文件链接到您自己的Sound.lib以及正确的OpenAL库文件，一切都会好起来。
